(3,4) And they can bind to erythrocytes,simultaneously with immune factors, causing hemagglutination and anemia. (5)Of the 119 known dietary lectins, about half are panhemagglutinins, clumping allblood types. The remainder are blood-type specific.
Two of the four cells will contain one recombinant chromosome. In eukaryotic cells, crossing over can also occur during mitosis. Somatic cells (non-sex cells) undergo mitosis to produce two distinct cells with identical genetic material.
The classical example of a change in phenotype associated with unequal crossing-over is the. X-linked Bar (B) locus of Drosophila melanogaster. A duplication of the 16A region of the X. chromosome gives th-eye mutation, where the eye is reduced in size to a narrow vertical bar e Bar.
